Sodium of Polyaspartic Acid  PASP CAS 181828-06-8

Product name: Sodium of polyaspartic acid

CAS No. 181828-06-8; 34345-47-6; 25608-40-6;

Molecular formula:C4H5NO3M(C4H4NO3M)m(C4H4NO3M)nC4H4NO3M2

PASP is an artificial biomimetic synthetic water-soluble polymer material with the characteristics of non-phosphorus, non-toxic, non-pollution and complete biodegradability, and is an internationally recognized "green chemical". Polyaspartic acid has strong chelating, dispersing, adsorption and other functions due to the structural characteristics of active genes such as peptide bonds and hydroxyl groups, and has excellent compatibility.

Specification conform to standard HG/T3822-2006

It has wide application in the field cosmetics, water treatment, agricultural fertilizers;

1. As a scale and corrosion inhibitor, it is widely used in industrial circulating water, boiler water, reverse osmosis water, oil field water, seawater desalination and other water treatment fields. It has high hardness, high alkalinity, high PH, high concentration Excellent performance in multiple systems, polyaspartic acid scale inhibition effect is better than commonly used phosphine-containing scale inhibitors. Polyaspartic acid and PBTCA have a synergistic effect after compounding. The formulated composite corrosion and scale inhibitor has good corrosion and scale inhibition performance, and can be used as a dispersant in the papermaking, printing and dyeing, and washing industries; as a humectant in the field of daily chemicals.
2. It could be used as a new type of daily chemical additives and various non-toxic and non-polluting special fine chemicals due to its environmental protection characteristics.
3. It is used as a nutrient absorption enhancer in agriculture. It is suitable for urea, compound fertilizer, water-soluble fertilizer, foliar fertilizer, drip irrigation, etc. It can promote the absorption of nutrients by crops, and promote vegetables, fruits, flowers, etc. In the production of crops, simultaneous use with pesticides can improve the efficacy.

We also could customized PASP with different salt
